CAN-TOP GUIDING- AND EJECTING MECHANISM.

Specification of Letters Patent.

Patented May 4, 1915.

Application filed July 2,1913. Serial No. 777,115.

To all fui/wm t may concern Be it known that I, FRED LEo FULLER, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented new and useful Improvements in Can-Top Guiding and Ejecting Mechanisms, of which the following is a specification.

My invention relates to guides for can tops of can capping and seaming machines and the ejectionof they finished can. In the adaptation of my improvements, the samek has been illustrated in connection with that type of can capping and seaming machines as shown in U. S. Letters Patent No. 1,055,467, wherein the filled cans are automatically fed from the can-top feeding station to the seaming station and wherein provision must be made, when handling cans containing fruit, etc., which protrude above the top of the can, to prevent the top from becoming displaced or tilted until such time as the top is in position to be seamed onto the can. While I have referred to the above U. S. patent, it is to be understood that my invention is not necessarily limited to that particular machine but may be applied to other types as well.

One of the objects of the present invention is to provide a guide for the can top between the time it leaves the cover-guide used in connection with a revolving turret and the time the can top shall be carried to its proper position under the seaming chuck. Difficulty has heretofore been experienced in canning high goods, e., fruit, fish, vegetables, etc., which stand up above the top of the can before the top is put on, the material to be canned causing the top to be tilted or misplaced and preventing thereby proper seaming. The device which is herewith described is intended to overcome this difficulty and at the same time to act as a stripper for thefinished can. With this device it is impossible to puncture the top of the can as is oftentimes the case with ejector rods as heretofore constructed. v

I attain these and other incidental objects by the mechanism illustrated in the accompanying drawings forming part of this specification, in which- Figure 1 is a sectional view through the drive shaft and double seam head of a single spindle fia-nger; Fig. 2 is a sectional View through the double seaming head and turret; Fig. 3 is an enlarged view of the upper part of my improved device to show the same more clearly; Fig. 4 is a view in elevation of same, and Fig. 5 is a diagrammatic view illustrating the adaptation of my device and showing F high fruit in the can.

Similar letters and figures refer to similar parts throughout the several views.

1 is a rod,-the lower end of which is provided With a can top guide or plateV 2, said.

rod extending through the hollow chuckspindle 3. 'Ihe lever 4 is pivoted on the fixed frame of the machine and is actuated at its inner end by a cam (not shown) see U. S. patent previously referred to, and rod Rpwithin the column C, the outer end of the lever being preferably forked and provided with studs 5. On the rod 1 is a collar 6 with set-screw 7 for securing same in fixed position, and above this is a sliding cross-bar 8 mounted on the rod and having studs 9. The forked ends of the lever 4 and the crossbar 8 are connected by a pair of links 10. Between the fixed collar 6 and the sliding cross-bar 8 is a sliding bushing 11 a little shorter than the distance between the collar and the cross-bar. Surrounding this is a spring 12 under compression bearing against the collar and the cross-bar. Also on the rod 1 and below the xed collar 6 is another bushing 13 which rests upon the chuckspindle jam-screw 14 in the column head of the machine; this bushing 13 limits the drop of the rod 1 and consequently fixes, in connection with the collar 6, the lowest position of the guide plate 2.

'Ihe operation of the device described is as follows z-The position of the guide plate 2 is normally as shown in Fig. 2. When a can top 15 (see Fig. 5) is about to leave the cover-guard 16 over the turret 17 the outer edge of the top 15 will come under the guide plate 2 before the top has been entirely withdrawn from under the c0ver-guard; should there be any high fruit or other high standing substance in the can, the top will not be displaced or tilted when the can rises for the reason that the top remains practically in the same plane as when leaving the cover-guard and is still retained in the can-top recess on the turret.

The can top having arrivedk at its proper position, the can is raised bythe elevating mechanism (not shown) which causes the the fixed collarv on lthe rodl is also liftedy causing the bushing 11 to be brought closer to the cross-bar 8, but not changing 'the relative position of the other `Vparts.V Vllen the can tcp and can have been seamed and the operation .has so liar advanced lthat the can is :to bepejected, the lever .4 is acted upon by ,a cam (noty shown) and rod R within kthe column Cof the machine, forcing lthe ,crossbar 8 which is kattached :tothe ends of fthe flever yby the links 10 1down against the bushfn'gjlflvwhich, .bearing-against Ithe -fxed collar f6, causes ,the irod l and guide plate 2 to Ybegiven ,afslight downward un- `yielding ,movement suicient to V:release the can from the chuck. As they sprling 1,2 ',is

under compression ait will carry :the ',plate 12.

,still ffa'rther down ,until stopped bythe kcol- 'lar 16 coming vin contact with'the bushing L3 j resting .on 'the column-head. The -fplate 2 is then in lposition to -gu'ide the succeeding canftop. 1 v

yHaving thus descmibed -1ny invention,

.what Iv claim vas new vand desire by Letters Patent' tosecure, is-v In a can capping apparatus of the class describedwherein the cans are automatically Vfed from Athecan-top feeding station to the seeming station'by means of a revolving turret, and wherein the can bodies wlth 1 their caps thereonare acted upon by astationary cover-guide, in combination with ,a ,hollow :Spindle having a recessed seam ing chuck on the lower. end thereof, a rod extending throughsaidhollow spindle and protruding .below said chuck,`.a guicleplate -necting said sliding cross-head to said lever at its extremity.
